The ex–One Direction singer, 23, and Corden, 38, joined guests Isla Fisher and Ewan McGregor for a round of “Spill Your Guts Out” — a game where one must either answer a tough question or eat something disgusting.

This isn’t the first time Horan has named the “Lights” singer his No. 1. During an appearance on The Ellen DeGeneres Show, he played a game of “Who’d You Rather?” and at the end, the “This Town” crooner chose Goulding over sexy stars such as Rita Ora and Kendall Jenner.

Horan was linked to Gomez in late 2015 and briefly dated Goulding in 2013. In a cover story for Seventeen’s April 2016 issue, the British songstress opened up about maintaining an amicable relationship with the boy-bander even after they split.

"We're still friends," Goulding told the mag. "We went on a few dates, and it was really fun. He's a really, really lovely guy. He's got the biggest sense of humor, he's very caring, and I see him as a genuine friend in the industry."
